Notes:1. The output power is rated at the condition THD+N
10%,1kHzsine wave.
2. All amplifier boards don't employ power supply reverse
polarityprotection. Stresses beyond the power supply range
maximumratings may cause permanent damage.
3. None typical load may cause rating power reduction.
4. Dimensions mean length and width of PCB only,
excludingexcessive part out of the PCB outline.
5. If any model within product series is out of stock, another
modelwith compatible size and function, featuring more rating
outputpower will be sent as the substitute without notice. For
example,*1 AA-AB32196's alternative model is AA-AB32314.*2
AA-AB32511's alternative model is AA-AB32431.
6. All parameters were tested with Rohde & Schwarz UPV
audioanalyzer (AES17 filter enabled) and APAUX0025 filter.
LinearPower Supply units were used for testing.
7. Sure Electronics promise all standard products life cycle
morethan 5 years. Sure Electronics reserve the right to update
theversion without notice. All the products sent to retail
customers arethe latest version. We will provide back-to-order
service (100Pieces MOQ needed) for our distributors in 5 years.
